PowerDsine awarded patent in China

Oct. 28, 2004 - Patent pertains to company's Power over Ethernet technology.

PowerDsine announced today it has been awarded a "spare pair powering" patent in China that further extends the company's patent portfolio in Power over Ethernet technology.

The patent No. ZL 99815577.2, issued under certificate 161478 in China, pertains to PowerDsine's PoE stand-alone midspan products that connect to an Ethernet switch to PoE-enable an enterprise network. The PoE midspan is designed to supply reliable, uninterrupted power to IP phones, wireless LAN access points, network cameras and other devices using existing Ethernet cabling infrastructure. Additionally, when used in conjunction with a centralized Uninterrupted Power Supply (UPS), the PoE midspan ensures continuous operation, even during power failures, to increase the overall performance and reliability of the network.

"This patent from China reinforces PowerDsine's pioneering efforts in Power over Ethernet technology," says Igal Rotem, CEO of PowerDsine. "We believe that there is tremendous growth potential for PoE in the Chinese market and receipt of this patent will enable PowerDsine to further pursue these potential opportunities. We have engaged a high-profile vendor to sell and market our midspan products in the Chinese market and are currently pursuing additional vendor relationships in an effort to maximize PowerDsine's reach within China."

Rotem says the Chinese patent for "spare pair powering" will add another block to PowerDsine's history of PoE innovation. In October 2002, the United States Patent and Trademark Office awarded patent No. 6,473,608 that pertains to PowerDsine's structured cabling system invention. The U.S. patent, much like the Chinese patent, addresses the process that detects all "power enabled" elements in the Ethernet LAN so that power can be distributed safely via data Ethernet cabling infrastructure to those elements without affecting legacy devices.

PoE is a technology for wired Ethernet. PoE allows the electrical power necessary for the operation of each end-device, to be carried by data cables rather than by separate power cords.
